The greenhouse gas emissions are measured in million tonnes of carbon dioxide equivalent (MtCO2e): environmental case study, UOS, UK

Question 2

This question carries 35% of the marks for this assignment.

Figure 1 shows how the greenhouse gas emissions from some sectors have changed in the UK from 1998 to 2020. It does not include all sources of greenhouse gas emissions in the UK during this period, such as industrial processes.

The greenhouse gas emissions are measured in million tonnes of carbon dioxide equivalent (MtCO2e). This unit is commonly used for large quantities of gas, such as carbon dioxide emissions.

Show descriptionFigure 1 Greenhouse gas emissions, million tonnes of carbon dioxide equivalent (MtCO2e), from some different sectors in the UK from 1998 ... Study Figure 1 and answer the following questions:

a. For each sector, outline the trends in the amount of greenhouse gas emissions from 1998 to 2020.
b. State whether Figure 1 tells you anything about the causes of the trends.
c. From Figure 1 estimate, to the nearest 5 million tonnes of carbon dioxide equivalent (MtCO2e), the amount of greenhouse gas emissions from each sector in 1998, and from each sector in 2020. Present the data in a table.
